lsubject of the King of Great Britain, and

resident of Easton, in the county .of Northampton and State of Pennsylvania,. have 'invented a new and useful Improvement in Mining-Machines, of which the following is a specification.

.My invention relates to improvements in mining n achines and is directed to machines which are Well adapted for use in operating upon coal.

My invention relates more `particularl'y `to improvements in coal cutting and loading machines and contemplates the provision of a truck on which is mounted a puncher, said truck alsolcarrying a conveyer so arranged that it 'will conveythe coal from the front of the machine to the rear of the same Where it may be removed to any desiredpoint. y

My invention further contemplates cer# tain improvements in the construction, form and arrangement ofthe several parts of aV 'eoal'cutting 'and loading machine whereby thecoal may be cut and loaded 'inl a very simple and effective manner.

sections may be connected by tie plates 3 and bolts 4 engaging abutting ends of the track rails 2, forforming a continuous track. I

The coal cutting and loading machine is adapted for movement along the track,-the body or platform of the said machine being' denoted' by 5 and its front and rear trucks by G land 7, which trucks carry the ,usual traction ivheelsS and arev pivotally connected to the body or platform 5.'

'.'lhe machine is preferably Inovedalong the track by providing a Winch 9 around which is vv'ound a rope or cable 10, the ends of which ropeor cable vlosing provided Wit-h hooks 11 for engaging. holes l2 in one of the track rails 2 at points to the front and rear of the winch, so that the machine is moved tothe front and rearraccording to the direction in which the winch is turned. This Winch is provided with a small gear is prevented from -turning in a reversedi rection, as, for inst-ance byproviding pawls 1G, 17, either one of which is fitted to engage the gear 14 according to whether the winch is to be held against movement in one or the opposite direction. A suitable brake` 18 is arranged to grip and release thel traetion wheels 8 of the rear truck 7 the handle 19 of which brake-is engaged by a-rack 20 for holding the brake in any desired adjustment.

The coal puncher cylinder is denoted b 2l and the pick by'QQ. The pick is operated by pulsating columns of air through flexible tubes Q3, 24, leading to the puncher cylinder 21. from the cylinder Z5 of a pulsator, which pnlsator vis loperated'by `a motor, such, for instance, `as a motor 9.6, the shaft 27 of f'which yelectric motor isl ,connected to the shaft 28of -the pulsator through gears 29, 30.

The coal puncher cylinder. 21 is longitudinally adjusted with respect to its trunnions 31, 32, as follows: The opposite sides ofthe cylinder 2l are provided with longitudinal undercut grooves 33,34, iwhichreceive the heads .85, 36, of bolts 37, 38.' Each of the bolts B'Tpasses through one of a series of holes 39 in the trunnionl, and itsend is each of the bolts 38 extends through one of a series of holes Lllin the trunnion 32 and its tot the cylinder 21 rigidlyv to the trunnion 32. By this arrangement the puncherL may be adjusted longitudinally to a limited extent with respect to its trunnions.

The puncher may be swung vertically into any desired angular position by the following mechanism: A worm gear 48 of ring form is frictionally held between the trunnion 31 and an outer ring 44, in the present instance, by providing a plurality of bolts 45 projecting from the trunnion 81 through the ring 44 and interposing springs 46 between the outer face of the ring44 and the heads 47 of the said bolts. The trunnions 31 and the ring 44 with the frictionally clamped worm gear 43, are rotatably mounted in the side frame 48 of a support 49 and the trunnion is rotatably mounted in the side frame 50 of said support. A ring 51 is secured by screw-bolts 52 to the side frame 48 with its inner edge overlapping the ring 44, thus serving as a keeper for retaining the trunnions in their position in the side frames of the support. -A worm `53 is slidably mounted on a vertical shaft 54, which worm meshes with the worm gear 43. This worm is yieldingly held in its normal position on the said shaft by springs 55, 56 interposed between the said worm and ,upper and lower ball thrust bearings 57, 58, respectively. The worm 5B, shaft 54, springs 55, 56 and the ball thrust bearings 57, 58, are located in Aa recess 59 in the side frame 48. The shaft 54 is rotated by a hand wheel 60 through intermeshing pinions 61, 62.

The coal puncher may be swung laterally into different desired angular positions by' the following mechanism: A worm gear 63 lof ring form is frictionally held between the support 49 and-a ring 64, in the present instance, by providing-a plurality of bolts 65 projecting from the ring 64 through the base of the support 49 and interposing springs 66 between the base of the said support 49 and the heads 67 of the said bolts. A ring 68 is secured to the body or'platform 5 byscrew bolts 69, the inner edge of which ring overlaps the `base of the support 49 for retaining the. support in its position. A worm 70 is slidably mounted on a horizontal shaft 71 and meshes with lthe worm gear 63. This worm is yieldingly held in its normal position by springs 72, 73, interposed between the Worm and side ball thrust bearings 74., 75. The worm 70, shaft 71, springs 72, 73, and ball thrust bearings 74, 75, are

housed within a recess 76 in the body 5 of the machine. This shaft 71 is rotated from a handwheel 77 through a sprocket chain 78 and sprockets 79, 80.

The means which I have shown for con` veying the coal from a point in front of the machine to a point t0 the rear thereof, is constructed, arranged and operated as folbetween the traction wheels 8 and then Overl the rear truck 7. The front conveyer belt roll 82 is mounted in 'the side of a conveyer trough 85 adjacent to the front end of-the said trough. The bottom 86 of this trough rests upon the bottom plate 1 of the* track when the conveyer is in use.

between the upper and lower porti-ons of the conveyer belt, which sectional partition plate A sectionalv transverse partition plate 87 1s interposed extends practically the entire distance from y the front roll 82 to the rear rolls 83, 84. The lower portion of the conveyer belt at the rear end of the machine, runs along and is supported upon the floor section 88. of the body or platform 5 and the lower v'portion of the conveyer belt at the front end of the machine runs along and is supported upon:

thebottom 86 of the conveyer trough v85. This trough may be raised a sufhcient distance to permit it to clear the tops of the.

track rails when the machine is moved from place to place and is supported in such raised instance, as providing a bail 89 hinged'to the conveyer trough andv arranged to be engaged.v

withl a shoulder 90 at the front end of the body or platform 5, for lsupporting the front end of the' trough in its raised position and providing the sides of the body or platform 5 with holes 91 for receiving one or more suitablebars 92 indicated in dotted lines in Fig.,8*, which may be inserted beneath the sectional partition 87 at the rear end of the` conveyer trough. The feed rolls 88, 84, are geared together by gears 93, 94, and grip the conveyer belt 81 between the `same so as to prevent the conveyer belt from slipping Ain case it becomes slippery.

The conveyer beltis driven frm the motor 26 as follows: The shaft 28 of the pulsator is provided with a bevel gear `driving connection 9 5, 96, with one member 97 of a friction clutch ofany well known or approved form, mounted on a cross shaft 98, the other clutch member 99 of which is iXedto rotate with the said shaft 98. A hand lever 100 is employed for clutching the member 97 to and 'releasing it vfrom the member 99, whereby the rotation of the shaft 98 is controlled. This shaft 98 is provided with a sprocket wheel 101 which is connected to-a sprocket wheel 102 on the shaft of the roll 84, by a chain 103. This friction clutch forms a slip connection between the motor. and endless conveyer so that if the 'a5 position by any suitable means, such, for' noeaaie conveyer should become clogged or uninten-` tionally stopped in its movement,the slipping of theclutch connection between it and the motor would absolutely prevent any :breakage of the parts.

sired point, the nut 10T may be tightened for rigidly mounting the front end of the body or platform 5 on the truck 6. The rear truck 7 is pivotally connected to the body or platform 5 of the machine by providing the truck with an uprising stud 109 which enters a lug 110 depending from the iioor section 88 of the body or platform The operation of the machine is as follows. The machine is moved along the track into proximity to its work. One end of the rope-or cable l() is then attached to the track rail ata distance in fron-t of the winch 9 and the other end of the said rope or cable is at'- tached to the track at a distance from the rear of the said winch. The operation of the winch will then permit the machine to be moved to a limited extent, toward and away from the work as may be desired. The conveyer trough may then be released from its raised position and the trough dropped down on to the track between the track rails 2, 2. The puncher may then be swung laterally and vertically either for the purpose of undercutting or for breaking down the' face of the coal as may be desired. These laterally and vertically swinging movements of the puncher may be accomplished by manipulation of the hand wheels 77 and 60.

ff The coal may now be shoveled on to the flat belt conveyer at the front of the machine. The conveyer belt may then. be moved by connecting its driving means with the motor titl for conveying Ithe coal from the point at'the front of the machine to the point at the rear of the machine where the said coal may be deposited into any desired receptacle, as for instance, into, thebuckets 104.gif an endless conveyer 105 driven from any suitable source of supply, and this conveyer may deposit the coal into a regular mine car or wagon. 1When the machine has eut the coal. as far as possible and the front wheels have reached nearly the end of the track, another short section. of track is laid in .front of the preceding section and is secured thereto by tie plates 3 and bolts li. lt will be seen that as the machine is moved forward or backward by the winch, the trough. of the belt conveyor slides along on the bottom plate 1 of the track section. v

A yielding Worm connection between the puncher cylinder trunnionsy and their support and bet-Ween the support and the body or platform of the 1nachine,iabsolutely prevents the breakage of the parts when the puncher strikes a glancing blow on the face of the coal, the said yielding connection permitting a slight rotary yield of the puncher in both a lateral and a vertical direction according to the direction of the glancing movement of the puncher. The worms will be automatically returned to their adjusted position by the springs engaging the worms as hereinabove set forth. The frictional clamping of the worm gears will permit the gears to slipv before they will break under any undue twistprevent any undue wear on the teeth of the gears owing to the slight working around `of y the gears', thus presenting new teeth to the action of the Worms. This frictional clamping of the Worm gears may be adjusted tov any desired degree of resistance. If the puncher is thrown out of its adjusted position to any considerable extent, the slipping of the gears will permit the puncher to remain in such position and still operate, thus absolutely preventing the breakage of any in this machine is the lateral adjustment of the puncher without the necessity of affecting the adjustment of its trunnions. The ball thrust bearings for the worm centering springs serve to materially lessen the effort of the machine.

By locating the conveyer as set forth, it will be seen that it is not in the way of the machine when it is working; that it may be the machine, and' that the very desirable able platform, a puneher mounted thereon,4 yielding means for swinging the puncher laterally and yielding means for swinging the puncher vertically.
